If this interaction between Ben Affleck and Christian Bale is true then wow.
"Before we started the movie I was getting my kid a Hallowe'en costume. My son is really into Batman," Affleck explained. "We went to a costume store in Los Angeles... it was pretty empty. And I was in the aisle and I heard this 'Oi!', and I turned around, and it's Christian Bale! "And there he and I were, standing in the Batman section." "I said, 'Do you have any tips?'," Affleck recalled. "'And he said: 'Make sure you can piss in that suit.'" Bale was also in the costume shop to buy his son a Batman suit, Affleck added: "He doesn't just hang out [in the Batman aisle]".
